Set Up

INPUTS - The Vplus series amplifiers allows you to use two types of input connectors per a channel, a XLR jack for balanced con-

nections and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output

signal from a mixer, cross-over or EQ to your Vplus series amplifier. A balanced connection is recommended for cable runs longer

that 20ft. When constructing your own XLR cables follow the pin configuration describe below for proper connections. For cable runs

shorter than 20ft. you may choose the 1/4” unbalanced input option. The 1/4” unbalanced input option may be more convenient for

most users due to the abundant supply of prefabricated cables available at your local audio dealer. You may use the two XLR “Input

Thru” jacks to jump a parallel connection to another amplifier or other device. For Example: Connect a XLR cable to the input of chan-

nel one. You may now connect a XLR cable from the channel one “Input Thru” jack to the input jack of another amplifier’s channel one

input. This will reduce the use of “Y” cables.

OUTPUTS:

Binding Post/Banana Plug - Connect your speakers to the binding post outputs on the rear of the ampliﬁer. The

speaker wire may be connect by bare wire (directly connected, usually for permanent connections), banana plug,

or spade connector. Connections are made to Channels 1 and 2 output’s for stereo mode or across the red termi-

nals of Channels 1 and 2 for Mono Bridge Mode.

Important Notice: Although a speaker will operate with the positive and negative leads plugged into either termi-

nal on the ampliﬁer binding post, be sure to plug the negative lead into the black terminal and positive lead into

the red terminal. Ensuring proper polarity will avoid speakers being out of phase, that can cause a loss of bass

response.

OPERATING MODES:

Stereo Operation - Page 10/Figure 9 details an example of a typical stereo set-up. Connect your inputs into channels one and two of

the amplifier. Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down

to their lowest level (full counter-clockwise). Turn your amp on. Turn your input source level up. Use your front gain controls to regu-

late the output volume. Be sure not to raise the volume to the clip level, however an intermittent clip signal is acceptable.

Mono Bridge Operation - Page 9/Figure 8 details a mono bridge set-up. Be sure your amplifier and all other audio equipment is pow-

ered down. Flip the Stereo/Mono Bridge switch to the Mono Bridge position. Connect an input signal to channel one. Connect your

speaker across the red output binding post on the rear of your amplifier. Turn your equipment on (your amplifier should always be the

last item you turn on). Apply an input source signal to your amplifier. Turn channel two gain up. Use the channel one gain to regulate

your amplifier output.

Bridged-Mono Mode Caution - The voltage across the output terminals of a bridged Vplus series amplifier may equal or exceed 100

volts RMS and may be as high as 130 volts. Use fully insulated CLASS ONE wiring, and the load must be rated for up to 2500 watts

(@4 ohms)

PROTECTION:

LIMITER - The Vplus series comes with a built in limiter. When the input signal overloads, the “CLIP LED’s” indicate a signal overload,

at this time, the master volume should be lowered to reduce distortion. If the input gain level is not reduced the built-in limiter will acti-

vate. During signal overload, the limiter will reduce the input audio signal enough to minimize the amount of clipping. A limiter takes

the gain of an overloading signal and reduces it, the reduction in gain reduces distortion that can cause damage to your speakers and

amplifier. During normal operation below clipping, and momentary clips on peaks, the limiter does not affect the audio signal and is

inaudible. It will allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. During excessive clipping

the limiter will reduce the audio signal enough to minimize the amount of clipping. When the input signal decreases enough that clip-

ping ends, the limiter will deactivate and cease its gain reduction. The limiter has a fixed threshold and can not be adjusted.

Safe Power Levels at Different Output Loads:

8-Ohm Loads: The amplifier can operate at practically any power level without risk of overheating. However, if it is pushed hard

enough to continually light the “CLIP ” indicator, the amplifier’s average output power can reach 150 watts.

4-Ohm Loads: If the “CLIP ” indicator flashes occasionally, the amplifier is approaching its maximum long-term power capacity. If it is

lit about half the time, the amplifier channel will probably go into thermal protection within a few minutes.

2-Ohm Loads: Except for an occasional flash, keep the “CLIP ” indicator dark to avoid overheating the amplifier channel. Clipping

should be kept to a reasonable minimum. An amplifier’s peak current draw at full output power into 2 ohms is several times what the

“normal ” draw is, but its various protection circuits will prevent this condition lasting more than a minute or two.

Short Circuit Protection - The Vplus series amplifiers all come with built-in Output Short Circuit Protects. The Output Short Circuit

Protection protects the output devices of the amplifier from short circuits and stressful loads. If your speaker lines short, the ampli-

fier automatically detects this problem and discontinues operation for that channel. If one side of your amplifier becomes shorted and

American Audio® - www.americandj.com - Vplus Series Amplifiers Power Amplifier User Manual Page 13

Download from Www.Somanuals.com. All Manuals Search And Download.

goes into protect mode, the other side will continue to operate normally. During short circuit protection,

the "Clip" LED and “Protect" LED will light simultaneously indicating amplifier fault. All channel output

during the “Short Circuit Protection" will be interrupted (i.e. no sound output). Short Circuit Protection

can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output

terminal of the amplifier to the speaker. If this line good, check the internal speaker connections and

components. A short circuit will usually be traced to a bad cable or a bad speaker component and is

rarely traced to the amplifier itself.

Thermal Protection - A single variable-speed fan on the V1000plus and dual variable speed fans on the V2000plus and V3000plus

amplifiers provide adequate cooling. During low level output the fans run at normal speeds. During high output and as heat raises,

(exceeding 90°C.), the fans will run at higher speeds to aid the cooling process. If the heatsink temperature exceeds 91°C., the ampli-

fier will mute until the amplifier cools down. When the amplifier cools below 90°C., the amplifier will return to normal operations. Be

sure not to operate your amplifier below the minimum load ratings to reduce the risk of overheating problems.

Input/Output Protection - The input circuits are isolated by 10k resistors. An ultrasonic network uncouples RF from the output and

helps keep the amplifier stable with reactive loads.

Operating Voltage (AC Mains) - The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage is

dangerous and may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your

amplifier.

Gain Controls - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to

adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion

during normal operation.

Low Cut Filter (V2000 and V3000 Only) - The low-cut filter removes extremely low frequencies from the audio signal that could cause

speaker distortion or damage. The dip switches on the rear panel allows you to enable or disable the filter for each channel, as well as

adjust either a 50Hz or 30 Hz cut-off. Always use the 50 Hz filter setting if you are using the amplifier to drive a distributed line system

(also known as a constant-voltage line, 70 volt line, etc.). The dip switches on the rear panel allows you to configure the low cut filter.

The diagram below detail the functions of each dip switch, the functions are also printed on the rear panel of the amplifier.

Configuring the Low Cut Filter:

Activating Low Cut Filters - Dip switches 1 and 4 activate and deactivate the Low Cut Filter. Channel 1 filters is

OFF

control by dip switch 1 and channel 2 filter is controlled by dip switch 4.

Low Cut Frequency Selector - When the Low Cut Filter is activated, dip switches 2 (channel 1) and 3 (channel

2) will control the frequency roll-off. When dip switches 2 and 3 are in the "ON" the filter will cut off frequencies

at and below 30Hz, when these dip switches are in the "OFF" position the filter will cut off frequencies at and

below 50Hz. Please note: Each channel operates independently of each other allowing each channel to have

different filter settings.
